• Any telegraphic description would simply say 2 peninsulas, 5 islands, 6 piers, marshlands and a scent of seawater. On the one side, the sea, on the other, before land, the estuary. The latter is located on Algarve's leeward between the sandy peninsulas of Ancão and Manta Rota to Ria Formosa, - The Natural Park occupies 18.400 ha - and is the most important wetland area on the south of Portugal, being separated from the sea by a cordon of barrier islands and fed in freshwater by small, seasonal water streams. Diverse habitats - dunes, marshlands, low tides, pine woods and agricultural areas - complete the set. Important area in terms of bird fauna and a varied marine fauna presence since the lagoon area works as a nursery to some marine species.

    This Protected Area is stage for several activities - bivalve culture, fish farming, salt production, sand extraction... - and object of intensive visits being on the tourist heart of Algarve. Cacela-a-Velha with its 17th century fort, cubist Olhão or Tavira with its scissor roofs crossed by the Gilão / Séqua, live side by side with the characteristic agitation of the Algarve of leisure and summer.

  • While you visit Barreta, Culatra, Armona, Tavira and Cabanas, the barrier islands that separate the estuary from the ocean, do not lose sight of the fragile balance of the whole system. Almost without showing, the estuary constantly changes shape. We recommend that you start your visit at the Interpretation Centre (Olhão), where you can find all the available information about the area.


    To observe the fauna leave early in the morning or a bit before dusk. Bring binoculars and a camera, if you have them. Always pay attention to the weather forecast and avoid performing activities in days of rain, thunderstorm or fog. Avoid going out by yourself, but, if you do, inform an acquaintance or a local entity of your departure and return. Use simple and comfortable clothes. Make outerwear, food, water, sunscreen and/or a raincoat available. You may also want to take a cellphone and flashlight (do not start a fire and don't dispose of cigarette butts incorrectly). Take precautions and use insect repellent. If you want to enjoy the beaches do not forget your bathing suit. Take special precautions when walking in moist and rocky areas, to avoid falling and do not act in a way that might endanger yourself or others. In case of an accident contact the emergency service 112.
